一、问题的提出 所谓海浪过程的数值模拟,就是根据预先给定的海浪过程的谱密度模拟出与之对应的海浪过程,然后利用它去研究各种有关的问题.例如,当研究多桩柱石油平台的结构物经受波浪影响时,可以把波浪对结构物的作用问题看作一个随机过程系,用几个点的联合海浪过程模拟来处理.文献[1]中,已给出单过程海浪模拟实现的方法步骤.但是,由于伪随 First, the problem raised So-called numerical simulation of the process of the sea is based on the spectral density of the pre-given wave process to simulate the corresponding wave process, and then use it to study a variety of related issues.For example, when studying the multi-column When the structure of an oil platform is subjected to waves, the problem of the effect of waves on the structure can be considered as a stochastic process that is modeled by a combination of several points of the ocean wave process simulation. In [1] a single-process wave is given Method steps to simulate implementation. However, due to pseudo-random
